Why are my puffer fish floating on the water surface? They are not dead, they've been acting like this ever since I removed the bubbles. Please help me.

    You removed the bubblers? Why? It might be that they are not receiving enough oxygen through their water. In addition to that, it could be any number of things. How large is your tank and how long have you had the puffers? They may have not acclimated to the tank yet or if the aquarium has not cycled enough it may be too unstable to help fish thrive. Also, puffers do somewhat better in brackish water as adults, so you may consider adding salt depending on their age.

Hello. I have a green spotted puffer fish. I have had him for a year now and he seems to be doing fine! He gets along with my other fish (1 molly and 2 Bumble bee gobies) Could I add another fish? Such as another Goby?

    Really depends on the attitude of the puffer.
  • Quinlynn - 2013-04-04
    Yeah but I heard that you could put stuff in the water or on the fish to help them heal along with their fins.

    They can be in either fresh, salt or brackish water. Just put some salt in the tank with them, it's easy to figure out it alleviates (removes) the stress from the fish. Mine gets along with bumble bee fish too that's in my opinion because they hide and stay low to the ground and blend in, and they are also fast so the puffers can't catch them. Once I hade a puffer with a Black moore (goldfish) they got along great then one day I put a fiddler crab in there. He nipped at the black moore and because of that my puffer killed the crab immediately.

Hi my name is Quinlynn. I have a large fifty gallon tank with my Indian puffer and my two spotted puffers. I have a problem. On my way home one of the spotted puffers has taken a bite out of the other what do I do to help heal this? Help.

    Well, as with any wound it will need time to heal. You could try putting in antibiotics to the water to reduce the chance of infection. Also keep an eye on the fish. If they continue to be aggressive towards each other the best thing to do is separate them into different tanks. Also, provide plenty of hiding places and plants so that they can each form their own 'territories'. This should reduce/eliminate fighting.

I am a beginner to the world of fish, and I think I know what I am doing, but want it to be verified.

Here's my setup: 30 gal tank with 2 Sunburst Mollies and 2 sunset platies. I have the temp controlled at 72-78 degrees, I have some big rocks (one big enough to provide shelter), and a few plants, as well as a Chinese dragon bubbler.

Here's my question: I added a Green Spotted Puffer to the mix. Is that ok? I went to WalMart, and their fish fact tag says that the puffer will be ok with Mollies. He seems to be swimming around the whole tank, not bothering other fish, but I am worried about it after reading this website. Any suggestions?

Also, you might not be able to help on this, but my male Mollie keeps picking on the female. I was told to expect them to mate, but it looks more like torture and not mating. It could be that I am a beginner (outside that of a Beta) and just do not know what to expect. Any help here would be appreciated as well!

Thanks in advance!

    You can click on the links attached to provide you with more detailed information on the fish you have selected. Just a note to say that it is recommended that if you have other fish with a Pufferfish, you have at least a 50 gallon tank. The puffer fella likes to nip at fins. He is not supposed to be agressive and he is supposed to get along with other fish but you need a larger tank. You need a bit of vegatation there for the fish to hide and play in, whatever. Two mollies mating (movie on U-Tube) looks like the guy is trying to slam her, push her and shove her. Weird to see but it must work. Now maybe yours are fighting so watch the movie and then you'll know for sure. Looks like they were fighting to me too.
  • Anonymous - 2011-04-20
    Hmm. I wasn't told that I would need a 50, but that could be the case. The little guy has been in the tank for about 3 hours now, and he is starting to warm up to it. He swims around a lot, and doesn't seem to bother other fish. He was almost completely grey when I added him, but now his head and some of his body is back to Green. I have a 10 gal that my Beta is currently residing in that I could move him to. I bought some live plants tonight as well, so within a few weeks I should have some more greenery. I currently only have plastic plants, good ole WalMart doesn't say anything about live plants being a necessity.
  • Charlie Roche - 2011-04-21
    Yep, the information says if you just have the puffer, then a 20 gallon tank is fine but if you are adding (or have) other fish, you would need at least a 50 gallon. Puffer fish also need something to wear their teeth down so snails or some such other hard food. The 10 gallon tank is too small for the puffwer, definitely too small if there is another fish in it.
    Did you find the move on Mollies on U-Tube? There is one on just gold fish also. Strange.
    Yes, you need some plants. Have fun and enjoy. Remember all these fish are going to get bigger. The mollies will probably go 4 - 6 inches.
  • Anonymous - 2011-04-21
    Yes. Well, I took Mr Puff to Petco and donated him. I decided that I didn't want to ruin his little life just because I jumped in without surveying the water first. I think once I am out of an apartment and have my bigger tanks I will go get another puffer and try again. Thanks for all your help!

    Oh, random question. How many more fish can/ should I put in this 30 gallon? Currently I have 2 Mollies and 2 Platies. Thanks!
  • Charlie Roche - 2011-04-21
    I am responding to the other email which tells me you took the puffer back. You are asking how many additional fish you can put in a 30 gallon tank with 2 mollies and 2 platies. If you think 1 inch per gallon (just as a rule of thumb) and subtract out for gravel, decorations etc a 30 gallon should leave you with about 27 gallons of swiming area. So the two mollies are 12 inches (as adults) and the two platies are 5 inches (as adults) which equals 17 inches. So you can add two other compatible fish whose adult size is not greater than 5 inches each. OK? Yeah probably best to take back the puffer. Good thinking on your part.
  • Dioafui - 2011-05-09
    You're fine, but the male fish will chase the female to death. You should have at least three females per male, because of his desire to pro-create. I don't know about puffers, but you spelled betta wrong.
  • nic - 2011-08-05
    Here's where you went wrong. NEVER buy fish from Walmart they are cruel to their fish. They all have an illness and are not healthy fish and Walmart does not have any idea how to care for fish. They just want to make money. I had gotten a mollie and it had 50 babies and think first about how big each baby gets. hope this helps.

    p.s get live plants like water sprites
  • brookes - 2013-03-17
    thats not true i bought mine from walmart and it was a little agrisssive at the first 4 days then it got calm it was just scared thats all. all i got to say is love your green spotted puffers. i mean who can't love that little pug face of there'!

Horatio and his teeth!! Following on from the overfeeding incident Horatio seemed off his food and was a nasty grey colour and not his usual interactive self. On looking at his face he appeared to be all teeth, his top teeth touching his bottom (GSP s have 4 teeth/beak for crunching shells). Googling puffer teeth showed I would need to trim them for him to eat or he would starve! Fearing he would die anyway I carried out the following procedure. I used a dish about 2 inches deep containing his tank water, about 1/2 pint, to which I added 3 drops of clove oil. I placed him into dish and gently rocked the dish until his fins stopped moving and he rolled onto his side. Then I fished him out in a net trimming his teeth with cuticle cutters (heart stopping stuff), steady hand required and not for the faint hearted! Once I had trimmed back a suitable amount I placed him back into his tank still in the net with the filter water on him until there was movement. About 20 minutes later he was swimming around. A day later he was looking a lot less grey and is now his playful self.

I have a dwarf yellow puffer sharing a tank with several other fish. I've noticed that he has gone completely black and almost lifeless. He keeps on resting on the live plant. Could you tell me if he is dying and if I can do anything to help him please?

    It is usually a water condition issue.  What is the salinity of the water?  Check all your levels.  These fish are very sensitive to conditions.
Mandy - 2013-01-20
I wish I had read up on the green puffer fish before buying him. I just have a 5 gallon with one neon and one guppy. When I got him at Walmart (yea I know I shouldn't have), the guy told me that a 5 gallon would be fine and that they usually do fine with tank mates such as the ones I listed. He also told me that they generally just eat fish flakes and that the ghost shrimp would be fine in the tank. However, before we even got home with him and the two ghost shrimp, he had eaten them. Now he has started to pick on my other fish. Needless to say, I have separated them and am going to sell him as I can't afford another tank and its maintenance. I wish Walmart would keep accurate information and an informative fish keeper or 2 if they are going to continue to have fish.

    I would call the store manager and speak to them.  They should give you your money back!

Hi I got new tank and I put in tetra water conditiner. So do you know if it's safe to put a green spotted puffer in it? (I have not acclimated it yet with fish.). Please help if you have info.

    First, how large is your new tank? You will want to a have a minimum of a 30 gallon aquarium to give a green spotted puffer a fair chance to thrive. Second are you planning to get a baby puffer? Juveniles will do better in a regular aquarium, however as they get older they do much better in a brackish environment - meaning you will have to start adding salt and keep it a proper salinity level. These guys can be tough to keep! So if you plan to keep a puffer just be prepared to change up its environment as needed.
  • derek - 2013-01-09
    It's a 20 gallon but back to the original question. I put in tetra water conditioner and on the back it said safe to put in any fresh water fish. But they are only freshwater for one part of their life. So what do you say?
  • Jeremy Roche - 2013-01-09
    It is safe to use.
  • Jasmine Brough Hinesley - 2013-01-09
    Yes it is safe to use. You would have to put it in every time you change the water and use tap water for a freshwater tank.

Hey can you people help me out here? I have 1 of these in a 12 gallon tank and 1 catfish. The pufferfish has been flipping and looping and swimming like crazy like its having a seizure or something then it stops and it look like it's dead but then it starts swimming again close to the ground. Does anyone know what this is or how this happens? Please respond it worries me.

    The same thing happened to my puffer so I called the pet store we purchased him from and they said he had a seizure or a hart attack and will probably not recover. Eventually it will die slowly from starvation so my boyfriend and I decided to be somewhat humane and flush it :( I hope you dont have the same ending result.... and who knew fish had seizures!! i didnt.
  • Jeremy Roche - 2012-08-23
    First check your water levels.  Some times amonia spikes will cause this.Maybe add so was to increase oxyen levels in the water?
  • Lisa - 2012-10-07
    It is your PH or the ammonia levels- if the PH is acidic or you have high ammonia levels it will cause your fish to act that way and they will die. You should do a 50% water change and add ammonia remover and make sure that PH is in at the 7.2 to 7.5 range.

    Keep in mind that GSP's are 'naked' (meaning they lack scales) on the stomach primarily, but also somewhat lack on the rest of the body. They're very suceptible to disease, and are sensitive to temperature change.
Thomas Herrick - 2012-11-20
I first got my 2 green spotted puffers about 2 years ago. They are SLOW growing, although so much fun to watch! Both of mine are about 3-3.5 inches long. Since their scales are small (Practically naked on the white underside) they are VERY suceptible to a number of diseases (especially the pasasitc ailment known as freshwater Ick.) Earlier said, they display multiple personalities. They're not aggressive, no matter what the websites say. The better word to use, is 'Curious.' They love exploring new places within the tank, and nip at small organisms (Snails, crustaceans) in nooks and crannies within the tank. HOWEVER, I don't reccommend them for tanks that have fish with elegant, flowing fins. They'd be ripped apart within at least a day. It's always good to buy them in pairs (or more) so they can have members of the same species to comfort them. As earlier stated, this is a fish with a LOT of personality, so it'll need 'friends.' All in all, it's a fun, easy fish to keep. Comfortable in tanks around 20gal or more, with lots of same species buddies. It'll eat ANYTHING, (Sometimes the fins of other fish) so only be slightly cautioned. Rating: 10 out of 10! I hope to have mine for years to come!

    Oh, and also, mine are in a 55 gallon freshwater river rock setup, with a GIANT comet goldfish, large rainbow shark, 2 large silver dollars, a Florida Freshwater channel catfish (about 7 inches right now), a sunset gourami, and a leopard synodontis catfish. That'll give you some good species ideas to refer to (they're primarily semi-aggressive, but they hold their own if nipped or annoyed.) They all get along great! :)
